System for face authentication and method for face authentication

Abstract

Provided is a system for face authentication which can operate separately for individual providers of face authentication service in a stable and efficient manner. The system includes: face authentication machines; an administrator terminal; a face management server for storing image data of registered users; and face matching servers, each configured to generate face feature amount data of a person to be verified from image data acquired from the camera of a face authentication machine and perform a matching operation by comparing the face feature amount data of the person with that of registered users. Prior to face authentication, data of associations between face authentication machines and face matching servers entered by an administrator is transmitted from the administrator terminal to the face management server.

 wherein the face authentication administrating device displays operation screens that set association information required for the face management server and the plurality of face matching servers, and 
 wherein the operation screens comprise:
 a first screen that receives first operations to register the respective matching groups;

 a first operation to store and accumulate face image data of users, in the face management server of the server device, in association with respective matching groups corresponding to organizations to which the users belong; 
 a second operation to generate face feature amount data from the face image data of the users and store the face feature amount data separately for the respective matching groups corresponding to the organizations to which the users belong, the second operation being performed by each of the plurality of face matching servers of the server device; and 
 a matching operation between the face feature amount data of the users stored separately for the respective matching groups and face feature amount data generated from face image data of a person to be verified, the face image data of the person to be verified being acquired by a camera of a face authentication machine, the matching operation being performed by at least one of the plurality of face matching servers of the server device, the at least one of the plurality of face matching servers performing the matching operation when acquiring the face image data of the person to be verified from the face authentication machine, and 
 wherein the operation screens comprise:
 a first screen that receives first operations to register the respective matching groups; 
 a second screen that receives second operations to set the association information regarding first associations between the respective matching groups registered by the first screen and the plurality of face matching servers; and 
 a third screen that receives third operations to set the association information regarding second associations between the users and the respective matching groups registered by the first screen, the third screen setting the association information regarding the second associations when face image data of a user is registered. 
 
 
     
     
       3. A face authentication administrating method for administrating a system for face authentication, the face authentication administrating method being performed by a processor of a face authentication administrating device, the face authentication administrating device to be operated by an administrator, the face authentication administrating method displaying operation screens that set association information required for operations performed by a face management server and a plurality of face matching servers, the operations comprising:
 a first operation to store and accumulate face image data of users, in the face management server of a server device, in association with respective matching groups corresponding to organizations to which the users belong, the server device including the face management server and the plurality of face matching servers, the server device being connected to the face authentication administrating device via a network; 
 a second operation to generate face feature amount data from the face image data of the users and store the face feature amount data separately for the respective matching groups corresponding to the organizations to which the users belong, the second operation being performed by each of the plurality of face matching servers of the server device when the face image data of the users is registered or updated; and 
 a matching operation between the face feature amount data of the users stored separately for the respective matching groups and face feature amount data generated from face image data of a person to be verified, the face image data of the person to be verified being acquired by a camera of a face authentication machine, the matching operation being performed by at least one of the plurality of face matching servers of the server device, the at least one of the plurality of face matching servers performing the matching operation when acquiring the face image data of the person to be verified from the face authentication machine, and 
 wherein the operation screens comprise:
 a first screen that receives first operations to register the respective matching groups; 
 a second screen that receives second operations to set the association information regarding first associations between the respective matching groups registered by the first screen and the plurality of face matching servers; and 
 a third screen that receives third operations to set the association information regarding second associations between the users and the respective matching groups registered by the first screen, the third screen setting the association information regarding the second associations when face image data of a user is registered.
